2.2 DESCRIPTION

The Patton Model 1010A miniature, high speed, transformer

isolated short range modem lets two asynchronous RS-232 devices

communicate between buildings, over two twisted pair. Supporting

asynchronous data rates to 115.2 Kbps, the Model 1010A derives the

necessary power for operation from the data and control voltages on

the RS-232 interface. DC transformer isolation on the line side gives

the Model 1010A immunity to ground loops that would otherwise

hamper between-building communications.

An external DCE/DTE switch lets you connect to the serial port of

either a computer/terminal (DTE) or a modem (DCE) without using a

crossover cable. The Model 1010A is available with three 4 wire

interface options: RJ-11, RJ-45 or terminal blocks with strain relief.

The Model 1010A also incorporates high speed avalanche diodes

that intercept data line transient surges and shunt them safely to

chassis ground. With surge handling capacity of 600W per wire at

1mS, the 1010A can protect itself and connected equipment from

nearby lightning strikes and other surges of electromagnetic radiation.

3.0 CONFIGURATION

The Model 1010A is designed to be easy to use. There are no

internal jumpers or DIP switches to set, so there is no need to open the

case to configure the unit (you may need to open the case for wire

connection—refer to section 4.0). The only configuration necessary for

operation is proper setting of the external DCE/DTE switch.

The figure below shows the location of the DCE/DTE switch on the

PC board, as well as the location of the terminal block and surge

suppressors.

3.1 SETTING THE DTE/DCE SWITCH

For your convenience, the Model 1010A has an externally

accessible DCE/DTE switch (see figure below). If the device connected

to the Model 1010A is a modem or multiplexer (or is wired like one), set

the switch to "DTE". This setting causes the Model 1010A to behave

like Data Terminal Equipment and transmit data on pin 2.

If the device connected to the Model 1010A is a PC, terminal or

host computer (or is wired like one), set the switch to "DCE". This

setting causes the Model 1010A to behave like Data Communications

Equipment and transmit data on pin 3.

4.0 INSTALLATION

Once you have properly configured the DTE/DCE switch, you are

ready to connect the Model 1010A to your system. This section tells

you how to properly connect the Model 1010A to the twisted pair and

RS-232 interfaces, and how to operate the Model 1010A.

4.1 CONNECTION TO THE TWISTED PAIR INTERFACE

The Model 1010A supports data-only communication between two

RS-232 devices at distances to 8.5 miles and data rates to 115.2 Kbps.

There are two essential requirements for installing the Model 1010A:

1) These units work in

pairs

. Therefore, you must have one Model

1010A at each end of a two twisted pair interface.

2) To function properly, the Model 1010A needs two twisted pairs of

metallic wire. These pairs must be

unconditioned

, dry metallic wire,

between 19 and 26 AWG (the higher number gauges may limit distance

somewhat). Standard dial-up telephone circuits, or leased circuits that

run through signal equalization equipment, are

not acceptable

For your convenience, the Model 1010A is available with three

different twisted pair interfaces: RJ-11 jack, RJ-45 jack and terminal

blocks with strain relief.

4.1.1 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45

The RJ-11 and RJ-45 connectors on the Model 1010A's twisted pair

interface are pre-wired for a standard TELCO wiring environment. The

signal/pin relationships are shown below:

RJ-1

1 SIGNAL RJ-45 SIGNAL

1...................GND* 1 .................N/C

2...................RCV- 2 .................GND*

3...................XMT+ 3 .................RCV-

4...................XMT- 4 .................XMT+

5...................RCV+ 5 .................XMT-

6...................GND 6 .................RCV+

7 .................GND

8 .................N/C

10. BEND the top half of the case as necessary to place it over the

strain relief assembly. Do not snap the case together yet.

11. Insert one captive screw through a saddle washer, then insert

the captive screw with the washer on it through the hole in the DB-25

end of the case. Snap that side of the case closed. Repeat the

process for the other side. This completes cable installation.

4.2 CONNECTION TO THE RS-232 INTERFACE

Once you have configured the Model 1010A for DTE or DCE and

connected the twisted pair wires correctly, all that remains is to plug the

1010A directly into the DB-25 port of the RS-232 device. After doing

so, remember to insert and tighten the two captive connector screws.

(Note: If you must use a cable to connect the Model 1010A to the

RS-232 device, make sure it is a

straight through

cable of the shortest

possible length—we recommend 6 feet or less).

4.3 OPERATING THE MODEL 1010A

Once the Model 1010A is properly installed, it should operate

transparently—as if it were a standard cable connection. Operating

power is derived from the RS-232 data and control signals; there is no

"ON/OFF" switch. All data signals from the RS-232 interface are

passed straight through. All control signals from the RS-232 interface

are looped back.

(Note: If your system requires

hardware

flow control, you will need the

Patton Model 1012 or Model 1060 Short Range Modem. Call Patton

Customer Service at 301-975-1007 for more information).

+RCV- G -XMT+

When connecting two Model 1010As, it is necessary to use a

"cross over" cable. The diagram below shows how a cross over cable

should be constructed for an environment where both Model 1010As

use a 6-wire RJ-11 connector. Similar logic should be followed when

using RJ-45 connectors or a combination of the two.

4.1.2 TWISTED PAIR CONNECTION USING TERMINAL BLOCKS

If your RS-422 application requires you to connect two pairs of

bare wires to the Model 1010A, you will need to open the case to

access the terminal blocks. The following instructions will tell you how

to open the case, connect the bare wires to the terminal blocks, and

fasten the strain relief collar in place so that the wires won't pull loose.

(continued)

8. Place the 2 halves of the strain relief assembly on either side of

the telephone wire and press together very lightly. Slide the assembly

so that it is about 2 inches from the terminal posts and press together

firmly. If your cable diameter is too small or too large for our strain

relief, please contact our technical support. We have strain relief

assemblies to accommodate most cable diameters.

9. Insert the strain relief assembly with the wire going through it

into the slot in the bottom half of the modem case and set it into the

recess in the case.

1. Open the unit by gently inserting a screw driver between the DB-25

connector and the lip of the plastic case (see below). You don't have to

worry about breaking the plastic, but be careful not to bend the D-sub

connector.

Once the unit has been opened, you will be able to see the

terminal blocks located at the rear of the PC board.

2. Strip the outer insulation from the twisted pairs about one inch

from the end.

3. Strip back the insulation on each of the 2 twisted pair wires

about .25".

+RCV- G -XMT+

4. Connect

one pair

of wires to XMT+ and XMT- (transmit positive

and negative) on the terminal block, making careful note of which color

is positive, and which color is negative.

5. Connect the

other pair

of wires to RCV+ and RCV- (receive

positive and negative) on the terminal block, again making careful note

of which color is positive, and which color is negative.

Ultimately, you will want to construct a two pair cross over cable that

makes a connection with the RS-422 device as shown below:

6. If there is a shield around the telephone cable, it may be

connected to "G" on the terminal block. To avoid ground loops, we

recommend connecting the shield at the computer end only. A ground

wire is

not necessary

for proper operation of the Model 1010A.

7. When you finish connecting the wires to the terminal block, the

assembly should resemble the diagram below:
